Seconds in Android callback

Hi Chris,

I noticed the seconds of `Recorded_At` property in the Android callback. The seconds were present in the [past](https://github.com/christocracy/cordova-plugin-background-geolocation/blob/11f19d864848746ebfa3cf3fcbe6a6c40f9440fb/src/android/data/sqlite/SQLiteLocationDAO.java) but recently truncated (ab3c2fadcd7a74c78d124780fd61c7a1296d60a4), if there's no specific reason, i'd like to have them back!
